This is the all new AMMO Pro Foamer designed for weekend warriors and mobile professionals. This is a 2.5 Gallon hand pump PLUS compressor-fed continuous foamer. You can hook it to your existing compressor for continuous foaming without pumping or simply put in the back of your mobile van or garage and pump by hand. Pour one full bottle of Frothe Concentrate into the Pro Foamer and fill to 2.5 gallons with water. This will give you the capability to clean 20-22 vehicles. Which is approximately $1.60 per full car hoseless wash! Has a 6 foot foamer nozzle and full air pressure value and gauge. This is a serious tool that will make your life 100x easier when cleaning without a hose/water. You can leave the remaining product in the Pro Foamer until used (do not allow unit to freeze).
